The ultimate pint - Fully tempered from rim to base for increased resistance to thermal and mechanical shock, ‘The Ultimate Pint’ uses the ‘Stress Fracture Management System’ to promote ‘reverse breakage’ when the glass is violently hit against another surface. This reduces the opportunity of using the glass to cause injury as the base is designed to fragment, thus dropping from the hand. Other benefits of 'The Ultimate Pint' include: o New performance 'Head Booster' nucleation options available o 100% recyclable as clear glass o Open design for increased airflow and quicker drying o Ergonomic shoulder for the hand to rest against. o UP TO 5 TIMES STRONGER o 10-15 TIMES LONGER LIFESPAN
